Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pressure detection output characteristics are predetermined at factory, then manufacturing simplicity is maintained, but user customization capability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-measuring and storing reference pressure detection output characteristics during manufacturing, then using these pre-prepared reference values for later adjustment processes. This allows the system to maintain simple manufacturing while enabling post-factory customization through adjustment based on the pre-stored reference characteristics.
2Measurement precision
If pressure detector components are used, then pressure detection function is achieved, but aging causes deviation in detection accuracy
Solution Approach 1:
The patent implements feedback by continuously comparing current pressure detection output characteristics against pre-stored reference characteristics, then automatically calculating and applying adjustment values to correct deviations. This closed-loop feedback mechanism compensates for aging effects and maintains detection accuracy over time.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the pressure detection output characteristics through calculated adjustment values that modify the detection parameters. This allows the system to adapt to aging-induced parameter drift by changing the operational parameters to maintain optimal performance.
3Adaptability or versatility
If adjustment mechanisms are added, then customization capability is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical adjustment mechanisms with computational methods. Instead of physical adjustment components, the system uses software-based calculation of adjustment values and digital modification of detection output characteristics, significantly reducing mechanical complexity while maintaining full customization capability.
Solution Approach 2:
The patent introduces an adjustment value calculation unit as an intermediary that bridges the reference characteristics and current detection output. This intermediary component simplifies the overall system by providing a dedicated function for calculating adjustments, making the complexity manageable and modular.
4Measurement precision
If reference characteristic measurement is performed, then adjustment accuracy is improved, but measurement time increases
Solution Approach 1:
The patent applies preliminary action by performing the reference characteristic measurement during the manufacturing process and storing these reference values for future use. This shifts the time-consuming measurement to the production phase, allowing rapid adjustments later without repeating the full measurement process.
Solution Approach 2:
The patent uses copying by creating a digital copy of the reference pressure detection characteristics during manufacturing and storing this copy for later comparison and adjustment. This eliminates the need to physically remeasure reference characteristics during adjustment, significantly reducing measurement time while maintaining accuracy.
